Composition for lining vessels



TATES COMPOSITION FOR LINING VESSELS.

:3PECIFICATION forming part of Letters Patent No. 380,853, dated April 10, 1888.

Application filed J'une 3, 1887. Serial No. 240,187. (Specimens) To all whom it may concern:

Be it known that I, J AMES ALVAH BLANCH- ARD, of the city of Brooklyn, in the county of Kings and State of New York, have invented a new and useful Composition of Matter, of which the following is a full, clear, and exact description.

My invention relates to a composition of matter for coating the interior of boxes, wrappers, or other casings and packages to fit them for use in inclosing compounds of a corrosive nature, either in a solid, fluid, or semi-fluid state; and its objects are to preserve the quality of the inclosed compound, to prevent access of air thereto and emanations of noxious gases therefrom, and also to prevent the inclosed compound from corroding and de stroying the wrapper or casing, and thus exuding and injuring or destroying adjacent and surrounding objects. 1

Chloride of lime is such a compound as I have above mentioned, and is an article in general use throughout the country for deodorizing, disinfecting, and bleaching purposes. l/Vhen exposed to the air, it evolves chlorine gas, which has a peculiarly pungent and disagreeable odor and is deleterious to health, and also has the effect of tarnishing metal articles which are exposed to its influence. Chloride of lime when so exposed to the air also absorbs moisture therefrom and becomes actively corrosive in its nature and destroys whatever envelops it, as well as whatever else it comes in contact with in its exit from its casing. For the reasons above stated its purchase and sale in either large or small quantities is undesirable, unless it is inclosed in wrappers or casings which will resist corrosion and prevent ingress of air or egress of gases to and from it. With a view to obviate these objections, metallic sheets and tin-foil have been made use of to inclose this chloride; but such is its corrosive action and so rapidly does it take place that, aided by the porosity of the inclosing material, holes are soon eaten in the box or package, the compound exudes therefrom, giving forth its noxious gas, injuring and destroying its surroundings, and when it is exposed to the air becoming useless for commercial purposes.

Boxes or packages constructed of wood or upon its surroundings as when inclosed in metallic sheets or tin-foil.

The object of my invention is to provide a comparatively inexpensive composition of matter the ingredients of which may be readily assimilated, and which may be quickly applied to the material constituting the box or package before or after the same is given proper shape, and thus preclude the entrance of air to the contained compound, the escape of gas therefrom, destruction or injury to the inclosing material, or exit of the compound itself, whereby compounds having the characteristics I have mentioned may be exposed for sale orkept in reserve without the attendant disagreeable features to which allusion has been made.

My composition of matter consists of the followingnamed ingredients, combined in substantially the proportions stated, namely: resin,eighty pounds; black pitch,sixtypounds; gypsum, forty pounds; petrolatum, twentyfive pounds, and combined in the following manner:

I first expose the resin and black pitch to heat in a kettle or other suitable receptacle, stirring them briskly as they melt, and when they have become liquefied and well mixed together I stir in the gypsum. hen the three ingredients have become thoroughly mixed, I add the petrolatum and stir the whole mass until all its components are completely assimilated. As the gypsum has a tendency to fall to the bottom of the receptacle when the liquid is at rest, the composition should J be well stirred before applying it to use. The

composition of matter thus produced is comparatively inexpensive, and by virtue of the nature and attributes of its ingredients and the manner in which they are assimilated, as herein described, when applied to the box or package, renders the same air-tight and proof IOC against the corrosive and disintegrative action of its contents, and also enables the package to Withstand any degree of cold and any degree of heat up to 120 Fahrenheit, applied externally. These properties of my invention allow of the employment in the construction of the receptacle of any of the hitherto ineffective materials and permit the casing to be used for inclosing compounds, either in a solid, fluid, orsemi-fluidstate, ofadisintegrative and corrosive nature, protecting them from the action of heat, cold, or air, and preventing their escape in a gaseous, solid, or fluid form.

The form of the receptacle, the material to be used in its construction, and the means and manner of fastening it after it is filled may be in each particular such as is deemed suitable and preferable to the manufacturer and packer, and my composition of matter may be applied to it in any suitable manner.

What I claim, and desire to secure by Letters Patent of the United States, is

As a new article of manufacture, the hereindescribed composition of matter for rendering air-tight and proof against corrosion Wrappers or casings for holding chloride of lime and like corrosive compounds, consisting of resin, black pitch, gypsum, and petrolatum, combined in substantially the proportions 3o herein specified.
